Special Containment Procedures: SCP-XXXX is to be contained in an observation chamber of height, width and depth of 5 metres. The chamber should contain the generic living requirements of avian animals, and it should be ensured that the food and water containers are filled daily. The chamber itself is to be cleaned once every other day. Only verified personnel may be allowed into the chamber. If researchers wish to conduct tests on SCP-XXXX, Dr [REDACTED] must either be present or absent during the test, depending on the nature of the experiment.

In the event of a containment breach, Dr [REDACTED] must be contacted at once to secure the subject. Other personnel are only authorised to approach the subject in the event of an emergency, but are warned that there is a high chance of injury.

Description: SCP-XXXX, nicknamed 'Harbringer' by Dr [REDACTED], has the appearance of a fully-functional, mobile avian skeleton. It has three toes on its right foot and four on its left - why this is as such is unknown, but it appears to be of no consequence. Its skull lacks the bottom half of its beak - however the subject appears to be unaware of this, as it has been observed attempting to scratch its bottom beak on numerous occasions. Its skeletal body is akin to that of a generic Corvus.

SCP-XXXX primary ability is its capability of altering the likelihood of unfortunate circumstances befalling those around it, hence its nickname. How the subject does this is still unknown, and currently there are no known methods to prevent its effect. Research is still ongoing.
Despite having no visible or physical wings other than the bones of its skeletal body, SCP-XXXX is capable of flight. Researchers have theorised this to be caused by its █████ of █████████, but this hypothesis lacks evidence.
Although never visibly observed, SCP-XXXX is capable of consuming food and water, and defecating. How it does this is unknown, as every attempted observation has had unfortunate circumstances occur that resulted in personell being unable to directly observe the subject as it did so. It is a possibility that this is purposefully executed by the subject through its primary ability.

Addendum: The subject's primary ability makes it exceptionally difficult to study, as Murphy's law appears to be implemented at all times - everything that can go wrong will go wrong. Many attempted tests and experiments have ended in failure due to malfunctioning machinery or unfortunately-timed events. While never resulting in death, these circumstances are still capable of bringing injury to personnel.

Although largely benign behaviour-wise, SCP-XXXX's primary ability is capable of causing serious injury and should always be handled with caution.
SCP-XXXX does not appreciate being experimented on. Despite this, SCP-XXXX is generally friendly to newly-introduced personnel until provoked via experiment or in general, at which great harm will likely occur to the provoker due to the subject's ability.

SCP-XXXX is exceptionally biased towards Dr [REDACTED], and tests have shown that the rate of occurances of the subject's primary ability decreases exponentially when the subject is in the presence of Dr [REDACTED]. This makes Dr [REDACTED] a valuable asset when dealing with SCP-XXXX, and as such the relationship between [REDACTED] and the subject must be preserved at all times.

Test 1A: A D-class staff member is to place the subject on a weighing machine to test if the subject weighs more than an average corvus skeleton.1A Result: Inconclusive. A localised power outage occured during the test, and the weighing machine failed to work afterwards due to a █████ of ████ from the █████████ that resulted from the darkness of the power outage.Comments:Likely caused by SCP-XXXX. He has proven himself to be a troublemaker in more ways than one…

Test 1B: Various personnel are to hold the subject and estimate its weight.1B Result: Largely varying estimations of weight that cannot simply be explained by human error. D-3243 estimated a weight of 12 kilograms, while D-2987 estimated a weight of 2.5 kilograms. [REDACTED] estimated a weight of 0.2 kilograms while D-3221 was incapable of carrying the subject due to its perceived weight. It may be of note that D-3221 was a cat burglar before becoming part of the SCP Foundation.
It is hypothesised that this ability of fluctuating weight is what enables █████.Comments:All personnel tripped and fell as they exited the chamber room after conducting the test. Including myself.

Test 2: Subject's source of water, its water bowl, is to be placed in a precarious position balancing on the edge of a thin stick that the subject is able to perch on. This is to test if the subject is able to alter the likelihood of an unfortunate occurance to itself, or something of its own interest.Results: SCP-XXXX's water bowl remained balanced for days on end, despite the subject landing and perching on the stick holding the water container to drink out of it. 32 hours after the experiment started, the water container finally fell and spilt its contents as the subject perched on the stick.Comments:Not only does this show that SCP-XXXX ,can change the likelihood of things for itself, but it also shows that it cannot change the likelihood of something to zero percent.

(WIP. To add :
-bad luck bird likes having fun, is a snarky crow guy

this is my first time writing an SCP so feedback would be greatly appreciated! idk how this site works tho lol)
